How to Measure Yourself

Use a soft measuring tape and stand naturally to take your measurements. It's best to measure over undergarments or close-fitting clothing.

  • Bust: Measure around the fullest part of your bust while wearing a bra that fits well.
  • Waist: Measure around your natural waistline — the narrowest part of your torso.
  • Hips: Measure around the fullest part of your hips and bottom (roughly 20 cm below your waist).

Between Sizes?

  • If your measurements fall between two sizes, we suggest choosing the larger size for a more comfortable fit — especially for tailored or slim-cut pieces.
  • For looser, relaxed styles, your usual size should be perfect.

Style + Fit Guidance

Every product page includes specific fit notes, like:

  • “True to size” for standard cuts
  • “Runs small – consider sizing up” for tighter fits
  • “Oversized fit” for looser silhouettes
